Sizing the circuit
A 48-amp charger on a 60-amp circuit gives the EV9 a comfortable overnight recovery even after a long day. The EV6 and Niro EV are perfectly happy at 32 to 40 amps for most households.
Where Indiana homeowners usually mount it
Attached garage, on the wall nearest the vehicle's charge port. For the EV9 the port is on the passenger rear quarter, which occasionally changes which wall makes sense — worth noting in your request.
